On January 10,  2019, SemGroup Corporation and KKR announced the formation of a joint venture to create SemCAMS Midstream ULC, a Canadian midstream infrastructure platform. The companies also announced that SemCAMS Midstream has entered into a definitive agreement to acquire Meritage Midstream ULC and its midstream infrastructure assets for $600 million.

Under the terms of the joint venture, SemGroup will contribute the shares and assets of its Canadian subsidiary, SemCAMS, valued at $1.15 billion, in exchange for $615 million cash proceeds and 51% common equity ownership in SemCAMS Midstream. KKR will contribute $515 million of cash in exchange for 49% of the common equity ownership. KKR will also contribute $300 million to acquire perpetual preferred equity. In addition, the joint venture will enter into a $800 million underwritten bank credit facility.

The transactions create a well-capitalized Canadian growth platform and expand SemGroup’s Montney footprint while deleveraging and strengthening its capital position.

SemGroup, headquartered in Tulsa, Oklahoma, moves energy across North America through a network of pipelines, processing plants, refinery-connected storage facilities and deep-water marine terminals with import and export capabilities.

KKR, based out of New York, is a leading global investment firm that manages multiple alternative asset classes, including private equity, energy, infrastructure, real estate and credit, with strategic partners that manage hedge funds.
